Diffusion Filters

A range of solutions for softening and spreading a light beam
and reducing the contrast ratio between highlight areas. The range
includes polyester diffusion filters, frosts, flexi-frosts, perforated diffusion,
grid cloths and spun materials all in different densities for a wide range of lighting effects.

Diffusions

Spread the projected beam of light over the subject, some loss of light will possibly be seen.
The greater the diffusion, the greater and more even the resultant spread of light. Shadows are reduced.
Used to smooth out beam scallops when lighting cycloramas or in tight spaces.
